APPARATUS FOR THE MANUFACTURE OF GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 414,727, dated November 12, 1889. Application filed April 29, 1889- Serial No. 309,104. (No model.)

To ctZZwhom it may concern.-

Be it known that I, HERMANN SoHULZn- BERGE, of Rochester, in the county of Beaver and State of Pennsylvania, have invented a new and useful ln'iprovement in Apparatus for the l'lanufacture of Glassware, of which the following is a full, clear, and exact description.

My invention relates to an improvement in apparatus for reheating and finishing glassware; and it consists, principally,in the combination, with a heating-furnace, of tools for receiving, holding, and revolving the articles.

My improvement is illustrated in the accompanying drawings, in which- Figure 1 is a vertical section through the furnace, together with the tools for holding, handling, and finishing the glass articles. Fig. 2 is a horizontal section of the furnace on the line 11 II of Fig. 1. Figs. 3 and a are sectional views of details.

Like symbols of reference parts in each.

The furnace, as represented in Fig. 1,comprises a combustion-chamber heated by gas, and an air-blast which of course may be re other suitable source for generating heat. The gas and air-blast are introduced by the adit-pipes-b for gas and m for blast-which are joined together in the gas-burnern, as shown in Fig. 1. By such arrangement a stronger heat can be produced with less fuel than is attained at present by the usual gas-burners used for such purpose in gloryhole furnaces. Furthermore, the gases of combustion do not have a reducing action upon the lead contained in articles made from lead-glass, if the proportion of blast to the amount of gas used is regulated so as to insure complete combustion of the gas before it meets and passes around the article under treatment. The gases of combution pass from the combustion-chamber through the fines c, which are provided with a vertical tile d or brick-work as the back thereof, and the openings 9 for introducing the glass articles to be reheated are located in front of such tiles. The tile, becoming indicate like heated to almost white heat, reflects and radiates heat upon the glass articles revolved in front of it, and thus materially quickens the operation of fire-finishin In front of the to by set-screws.

openings, journa-led in suitable bearings, are the supporting-rods I), each of which, as indicated by Figs. 1 and 2, is provided with a cup and a recess to receive the lower end of lam p-chimncys or other articles of which the top part is to be fire-melted or fire-finished. In place of such bowl-shaped supportfor the glass article to be reheated, a common snap or other suitable catch may be substituted. Each of the supporting-rods b is provided with a groove or key-seat, and is capable of sliding axially through a pulley 7;,which in its bore is provided with a key entering the groove in the supporting-rod. The pulley forms one of the bearings of the supporting-rod and is revoluble in the stand or post 72., as shown in Fig. The supportingrods b are also provided with collars or sleeves 0, attached there- Such sleeve is provided on its on ter side with an annular groove, in which fits a yoke or cross-head p, as shown in Fig. 4:. By this arrangement the supporting-rod may be revolved without necessarily revolving the yoke or cross-head. This crosshead is connected by links q and levers r or similar means attached to an axle s,which is journaled in the standard h. To the axle sis also attached the. hand-lever t, and it is evident that if said hand-lever 1- be raised or lowered the supporting-rods I) will be moved toward or away from the glory-hole, whether they be revolving or whether they be at rest.

Connected to the axle s is acounter-weight u on the arm n, which facilitates the backward-sliding motion of the supporting-rod. The axle s is also provided with a disk or ratchet-wheel {I}, which is engaged by the pawl y, so that if the axle s be turned the pawl y prevents it from moving back, and thus holdsthe supporting-rod in its new position until the pawl y be raised, when the counter-weight a will cause the supportingrod Z) to slide back. The function performed by the counter-weight u may likewise be performed by a coiled spring placed around the supporting rod and acting with one end against the pulley 7t and with its other end against the collar or sleeve 0, as indicated at z in Figs. 1 and 2.

The various pulleys of the several supporting-rods are connected together and with a common driving-wheel by a belt 2,which belt,

rricn.

1 after passing from the common or main driving-pulley, passes in succession around each pulley of the supporting-rods, it beingguided so as to move in any required direction by guide-Wheels 3, which, as represented in Fig. 1, are preferably placed below the floor, so as to cause the belt to travel around the furnace and move the supporting-rods without interfering with the accessibility of the glory-hole or of the supporting-rods.

The belt has advantages which cannot be attained by any other mechanical device for transferring motion for this purpose, because it runs more smoothly than any other gear ing and is not liable to cause distortion of the glass article when the latter is heated to a melting-point,which easily happens if the motion is transferred by cog-wheels or by miter-gearing. The use of the belt has also 1he advantage of being'applicable to revolving the supporting rods in any position, whether Vertical, horizontal, or inclined, and whether the supporting-rods are placed radially to a round glory-hole furnace, or whether they are arranged in a straight line and at various levels. In all cases one and the same belt may set in motion the whole set of supporting-rods, whatever may be their various positions relatively to each other or to the glory-hole. Although this movement might possibly be accomplished by gear-wheels, miter-gearing, and other gearings, it is evident that, aside from the objection mentioned above, such gearing would complicate the arrangement around the glory-hole so much as to be undesirable.

The apparatus may be modified in form and relative positions of the parts by those skilled in the art. For example, the gloryholes maybe situated so as to be accessible from below instead of making them accessible only horizontally.

1. An apparatus for reheating glassware, consisting in the combination, with a furnace having a combustion-chamber, and a discharge-flue provided with a vertical tile or brick-Work at its back, and a glory-hole or opening in front of the tile, of a revoluble supporting-rod located in such position as to place the glass article supported by itin front of the tile, substantially as and for the purposes described.

in front of the tile, in combination with a revoluble supporting-rod locatedin such position as to place the glass article supported by it in front of the tile, substantially as and for the purposes described.

3. In apparatus for reheating glassware, the combination, with a furnace havinga combustion-chamber or tlue provided with a plurality of glory-hole openings, of a plurality of supporting-rods revoluble in line with the glory-hole openings, and a single driving mechanism for the various supporting-rods, which driving mechanism consists in a belt connecting in a single circuit a driving-pulley with the various pulleys of the supporting-rods, substantially as and for the purposes described.

4. In apparatus for reheating glassware, the combination, with a furnace havinga combustion-chamber or flue provided with a plurality of glory-hole openings, of a plurality of supporting-rods revoluble and sliding in bearings-stationary with relation to the gloryholes, and means, substantially as described, for moving the supporting-rods toward and away from the glory-holes, and a common driving mechanism consisting in a belt connecting in circuit a driving-pulley with the various pulleys of the supporting-rods, substantially as and for the purposes described.

5: In apparatus for reheating glassware, the combination, with a supportingrod revoluble and sliding in bearings stationary with relation to the glory-holes, of a collar upon the supporting-rod, connected to an axle by levers or links, and a counter-weight to facilitate the sliding operation of the supporting-rod toward and away from the gloryhole, substantiallyasand for the purposes described.

In testimony whereof I have hereunto set my hand this 22d day of April, A. .D. 1889.
